Abstract

On récupère le nickel contenu dans des minerais d'oxyde en lessivant ces minerais avec de l'acide sulfurique. On délaye le minerai avec de l'eau, on le chauffe préalablement à une température de lessivage comprise entre 230 et 300 degrés C environ, et on introduit la bouillie préchauffée dans un autoclave ou une série d'autoclaves vigoureusement agités. On ajoute l'acide sulfurique par fractions à la bouillie préchauffée pour réduire au minimum la quantité de fer et d'aluminium en solution jusqu'à ce que d'environ 0,15 partie à environ 0,8 partie d'acide par partie de minerai sec ait été ajouté à la bouillie, ce qui permet de réduire au minimum le dépôt de tartre dans les autoclaves. Traitement des limonites et des silicates nickélifères.The nickel contained in oxide ores is recovered by leaching these ores with sulfuric acid. The ore is diluted with water, preheated to a leaching temperature of between 230 and 300 degrees C, and the preheated slurry is introduced into an autoclave or series of vigorously stirred autoclaves. Sulfuric acid is added in portions to the preheated slurry to minimize the amount of iron and aluminum in solution until from about 0.15 part to about 0.8 part of acid per part of Dry ore has been added to the slurry, which minimizes scale deposition in the autoclaves. Treatment of limonites and nickel silicates.
